no they come loose...i went through 60 bottles total of various types of their gear and no complained at all...hell for the price you cant beat it so i gave it a shot, and it turned out to be a good move. their tren is so clean i was really impressed by that. the bottles remind me of mexi-pharm. that was some cheesy ass shit, but was top notch....anyhow you guys can decide for yourselves, but its good in my opinion....ok gotta go eat, be safe alll jimmy58
